Trait ToUsize 

pub trait ToUsize {
    // Required method
    fn to_usize(&self) -> usize;
}

Helper trait to convert numbers to usize.

By default, usize implements From<u8> and From<u16> but not From<u32> and From<u64> because that would be invalid on some platforms. This trait implements the conversion for platforms with 32 and 64 bits pointer platforms

Required Methods

fn to_usize(&self) -> usize

converts self to usize

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
